Before a new type airplane goes service, every part of it is tested again and again. But there are two tests that are more of into important than the others.
The first is called the “tank test”. A modern airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure(压力)on a small window is like a huge foot that is trying to get out. If a small part of the plane were to fail, the plane would explode in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air. The pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger.
The most dangerous test happens when the new plane is going through test flights in the air. The test must find out exactly what happens when the engines(发动机) are all shut off at once. The plane begins to fall like a stone. It is the pilot’s job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers.
小题1:By doing the “tank test”, the engineers can find out ____.
| A．the amount of air in the plane | B．the strength of the plane structure |
| C．the pressure inside and outside the plane | D．the power of the airplane engines |
| A．It will be broken | B．It will be made stronger. |
| C．It will be filled with water. | D．It will be tested by pilots. |
| A．The plane may explode in the air | B．The pilot may lose control of the plane. |
| C．The engines may be damaged. | D．Too much air may get into the plane. |
| A．Two Important Tests on Airplane | B．The Importance of Flying Safety |
| C．The Danger of Testing Airplanes | D．How Airplanes Are made and Tested |
答案
小题1:B
小题2:A
小题3:B
小题4:A
解析
小题1:本题考查考生对文中细节的理解程度。“tank test”的目的就是为了查找出飞机压力，从而更好加固易损部位，以确保高空飞行时的安全性。
小题2:本题考查考生对文中细节的捕捉能力。第二段中提到“Finally, there is an explosion”,由此可见，在实验最后飞机会爆炸。
小题3:本题考查考生对文中细节的捕捉“It is the pilot’s job to find out how he can get control of the plane again”,而如果飞行员失误的话，则可能造成飞机失控，机毁人亡，因而test flight最危险。
小题4:本题考查考生对全文理解基础上综合概括能力。纵观全文，作者讲述了两个重要的飞机测试，脉络清晰简明。

举一反三
If you are a recent social science graduate who has had to listen to jokes about unemployment from your computer major classmates, you may have had the last laugh. There are many advantages for the social science major because this high-tech “Information Age” demands people who are flexible(灵活的) and who have good communication skills.
There are many social science majors in large companies who fill important positions. For example, a number of research studies found that social science majors had achieved greater managerial success than those who had technical training or pre-professional courses. Studies show that social science majors are most suited for change, which is the leading feature(特点) of the kind of high-speed, high-pressure, high-tech world we now live in.
Social science majors are not only experiencing success in their long-term company jobs, but they are also finding jobs more easily. A study showed that many companies had filled a large percentage of their entry-level positions with social science graduates. The study also showed that the most sought-after quality in a person who was looking for a job was communication skills, noted as “very important”, by 92 percent of the companies. Social science majors have these skills, often without knowing how important they are. It is probably due to these skills that they have been offered a wide variety of positions.
Finally, although some social science majors may still find it more difficult than their technically trained classmates to land the first job, recent graduates report that they don’t regret their choice of study.
小题1:By saying that “you may have had the last laugh” in the first paragraph, the author means that you may have____.
| A．shared the jokes with computer majors | B．earned as much as computer majors |
| C．found jobs more easily than computer majors | D．stopped joking about computer majors |
| A．are ready to change when situations change | B．are better able to deal with difficulties |
| C．are equally good at computer skills | D．are likely to give others pressure |
| A．keep for some time | B．successfully get | C．immediately start | D．lose regretfully |
| A．Willingness to take low-paid jobs. | B．Readiness to gain high-tech knowledge. |
| C．Skills in expressing themselves. | D．Part-time work experience. |
Indoor air pollution can cause a person to feel tired, to suffer eye-pain, headache and other problems. Some pollutants（污染物） can cause breathing disorders, diseases of blood and even cancer, Most scientists agree that every modern house has some kind of indoor pollution. People began to notice the problem in the early 1970s. It is that when builders began making houses and offices they did not waste energy. To do this they built buildings that limited the flow of air between inside and outside. They also began using manmade building materials. These materials are now known to let out harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building— green plants. Scientists do not really know how plants control air pollution. They believe that a plant’s leaves absorb or take in the pollutants. In exchange the plant lets out oxygen through its leaves and through its tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square metres of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and more healthy place.
小题1:Generally speaking, indoor air pollution may be more harmful than the air outside because ________.
| A．the man - made building materials let out dangerous gases inside houses |
| B．there may be more harmful gases outside houses |
| C．the flow of air indoors is limited |
| D．indoor air pollution can make a person seriously ill |
| A．they may let out more oxygen which people need |
| B．they can absorb different kinds of the harmful indoor chemicals |
| C．they can take in all kinds of indoor pollutants |
| D．they can make your house prettier and more healthy |

Scientists are using powerful radio telescopes to listen to signals from about 1, 000 stars, all within 100 light years of earth. In addition, they will scan（扫视）the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal they stands out from the background noise.
Of the 200 billion stars in the Milky Way galaxy（银河星系）, scientists find that five percent are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution（进化）of life. Based on the inhabitable（that can be lived in）planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.
However, many scientists wonder whether intelligent（有智力的）life exists on other planets. Some believe that twenty years of searching without any intelligible messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.
Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family is only about five billion years old, our galaxy is about 20 billion years old. In that time, some scientists think it is likely that civilization（文明）much more advanced than ours have developed. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.

The most proper answer would be (c) because the person in front of you is only a tourist trying to enjoy himself. The de¬vice is said to be the world’s first portable(便携的) translator — a hand-held microcomputer that at the same time translates one spoken language into another. The four-pound, battery-op¬erated product is called the Voice, and it is the invention of Advanced Products and Technologies, an American electronics company. When the Voice is introduced in the Unite States in late April — at a price of (1,500 — it will be used to trans¬late spoken English into Italian, German, French and Span¬ish. The product comes with separate cartridges(盒式存储器) for each of the four languages, which can be changed when the user travels from one country to another. It will be sold in Eu¬rope soon after the US introduction, with cartridges that trans¬late Italian, German, French and Spanish into English.
The Voice uses a microchip(微型集成电路片) to trans¬late languages. It is Started by voice command and produces voice output through a built-in speaker. When the user makes a statement or asks a question, the Voice immediately repeats what has been said in another language.
1. The device held by the stranger is probably a kind of________.
